Struct cpuio::UnsafePort

pub struct UnsafePort<T: InOut> { /* fields omitted */ }

An unsafe I/O port over an arbitrary type supporting the InOut interface.

This version of Port has unsafe read and write functions, and it's appropriate for speaking to hardware that can potentially corrupt memory or cause undefined behavior.

Methods

impl<T: InOut> UnsafePort<T>

const unsafe fn new(port: u16) -> UnsafePort<T>

Create a new I/O port.

unsafe fn read(&mut self) -> T

Read data from the port.

unsafe fn write(&mut self, value: T)

Write data to the port.
